Acquired second hand, probably from the Tavistock Iron Works around 1820-25, these are the last surviving authentic water-powered trip hammers, still working in England. The two huge hammers, one three quarters of a ton the other one and a quarter tons were used in the mass production of the Finch’s ‘edge tools’. When in full production the smaller steeling hammer, would beat at two hundred and forty beats per minute - four every second!
Trip Hammer (steeling) - One of two large water powered, belt driven mechanical trip hammers. (left hand side) Secondhand, probably from the same Tavistock ironworks that employed the Finch's before they started the Foundry. The striking plate and anvil base almost certainly renewed several times.
